JOHN B. SALO, OF BYESVILLE, OHIO.

NAIL-FULLER.

SPECIFICATION forming part of Letters Patent No. 686,540, dated November12, 1901. Application filed April 2, 1901. Serial No. 55,021` (Nomodel.)

To @ZZ whom `it may concern."

Be it known that I, JOHN B. SALO, a citizen of the United States, and aresident of Byesville, in the county of Guernsey and State of Ohio, haveinvented a new and Improved Nail-Puller, of which the following is afull, clear, and exact description.

This invention relates to improvements in nail-pullers; and the objectis to provide a nail-puller of simple construction that may be readilyengaged with a fastening-nail ot' a box or the like and then by acontinuous rotary motion draw out the nail. 4

I will describe a nail-puller embodying my invention and then point outthe novel features in the appended claims.

Reference is to be had to the accompanying drawings,'forming a part ofthis speciiication, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side view, partly in section, of anail-puller embodying myinvention. Fig. 2 is a front view, and Fig. 3 is abottom View, of thesame.

Referring to the drawings, 1' designates a frame, from which a leg 2extends downward to be engaged with a box or other device from which anailis to be drawn. Mounted to slide and to have vertical movement inbearings 3 on the frame is a draw-rod 4, and to permit of the upwardmovement of this draw-rod a handle 5,which is connected to the frame 1',is made tubular, as clearly indicated in'. Fig. 1.

Mounted on a shaft 6, which has a bearing in the frame 1,is a bevel-gear7, meshing with abevel-pinion S, mounted on the draw-rod 4. This pinion8 is designed to impart a rot-ary motion to the draw-rod but thedraw-rod is movable vertically through the pinion. For this purpose thedraw-rod is provided. with a slot 9, into which a feather on theinnerrside of the pinion may pass. From a wrist-pin 10 on the bevel-gear7 a link 11 extends to a connection with a lug 12, att-ached to thedrawrod.

Attached to the lower end of the draw-rod is a shell 13, and pivoted ona cross-bar 14 in said shell are jaws 15 and 16. The upper ends of thesejaws have link connections 17 and 18 with the lower end of the draw-rod.The jaws 15 and 16 `extend downward substantially to a point,andtheinner surfaces are corrugated, as at 19, so as to firmly grasp thehead of a nail. On the outer surfaces the jaws have threaded portions20, designed to cause the jaws tofeed into the wood, and said outersurfaces also have auger-like cutting edges 21. It will be noted thatthe teeth on the gear 7 extend only partially around the same or form asegment of a circle.

In operation to draw a nail the jaws when slightly separated are engagedwith the wood at opposite sides of the nail-head and with the leg 2,resting on the wood or box, and upon rotating the shaft 6 by means ofthe crank 22 thereon the segmental gear will rotate the pinion 8,consequently rotating th/e jaws, which will feed downward into the wood.Then after the teeth of the segment-gear shall have become' releasedfrom the pinion and the rotary movement of the gear 7 is continued thelink 11 will cause the draw-rod to move upward, and the links 17 and 1Sby being drawn upward will cause the jaws to engage tightly with thehead of the nail, so that said nail will be drawn out as the rod movesupward.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A nail-puller, comprising a frame, a leg on saidframe, a rod movable vertically in the frame', jaws on the lower end ofsaid rod for engaging with the nail-head, a wheel mounted in `the frameand having a segmental row of gear-teeth, a pinion on the lrod withwhich said gear-teeth are designed to engage, the rod being adaptedto'slde through the pinion but to rotate therewith, and a linkconnection between the wheel and the rod, substantially as specified.

2. A nail-puller, comprising a frame, a leg extended downward from saidframe, a drawrod movable vertically and having a rotary movement in theframe, pivoted jaws at the lower end of said rod, link connectionsbetween the upper ends ot the jaws and the rod, a bevel-pinion mountedon the rod and through which said rod may slide, a segmental bevel-gearfor engaging with said pinion, and a link connection between thesegmental bevel-gear and the rod, substantially as specified.

3. In a nail-puller, a frame, a leg extended downward from the frame, arod having slid- IOO W' I p ing movement in the frame and also adaptedimparting rotary and vertical movement t0 torotate therewith, means forimpart-ing the the draw-rod, substantially as specified. rotary motionto said rod and also a longitu- In testimony whereof I have signed my vdinal motion, pivoted jaws at the lower end name to this specificationin the presence of 5 of said rod and havinglink connection theretwosubscribing witnesses.
